  • an object of the present invention is to provide a natural discharge type water closet, in which flushing water with waste is discharged in a natural manner, so as to reduce the consumption of the flushing water and the noise during the discharge of the flushing water with waste.
  • Another object of the present invention is to provide a natural discharge type water closet, in which a modified bowl can be easily manufactured by selecting a proper position of a waste discharge pipe.
  • a water closet in accordance with the present invention, the water closet comprising: a bowl having a water supply channel and a discharge channel, the discharge channel being declivous in a backward direction of the bowl, so that waste and flushing water can be discharged in a natural manner; a waste discharge pipe interconnecting the discharge channel and a waste box; a waste discharge pipe plug installed in the waste discharge pipe in such a manner that the waste discharge pipe plug can move up and down in the waste discharge pipe; a water tank having a water discharge port in communication with the water supply channel of the bowl, a water supply port connected to a water pipe, a water discharge port-opening/closing plug for selectively opening and closing the water discharge port, and water supply port-opening/closing means for blocking the water supply port at a full water level and opening the water supply port prior to the full water level by a float rising and falling pursuant to a water level; a water tank-opening/closing lever pivotally disposed within the water
  • the waste discharge pipe plug comprises a plug body; a rubber packing screwed to a lower portion of the plug body with a certain gap from the lower portion; and a downwardly open casing which covers the plug body together with at least the gap.
  • the plug body and the rubber packing preferably have a through hole penetrated in a longitudinal direction, respectively and an auxiliary pipe having a hook-shaped flow channel is mounted to an upper end of the through hole of the plug body. Accordingly, the water closet in accordance with the present invention can not only obtain effects of water saving and noise reduction by discharging the flushing water including the waste in a natural manner not a forced manner, but also can make it easy to modify a shape of the closet by improving a position of the waste discharge pipe.

  • Figs. 2 to 4b are perspective and sectional views showing constructions and operative states of a natural discharge type water closet in accordance with the present invention.
  • a water supply channel 12 is formed along an upper end of a bowl 10, and a discharge channel 14 is formed at a lower portion of the bowl 10 in such a manner that the discharge channel 12 is declivous in a backward direction of the bowl 10, so that waste and flushing water can be discharged in a natural manner.
  • a waste box 16 embedded in the underground is located under the bowl 10, and the waste box 16 is connected to the discharge channel 14 of the bowl 10 through a waste discharge pipe 18.
  • This waste discharge pipe 18 is located at a center of the width b of the bowl 10 as stated below, which reduces restrictions in a modification of left and right side shapes of the bowl 10. That is, if the waste discharge pipe 18 is located leaning to one side of the bowl 10 as is in the existing water closet, it is impossible to modify the left and right side shapes of the bowl because the waste discharge pipe can be exposed to the exterior of the bowl 10 so that the beauty of the closet is spoiled in a front view of the bowl 10. On the contrary, if the waste discharge pipe 18 is located at the center of the width b of the bowl 10, it goes without saying that the both sides of the bowl 10 can be slimmer in so far as the waste discharge pipe is not exposed. Also, provided is a waste discharge pipe plug 20 capable of moving up and down within the waste discharge pipe 18 and having dimensions occupying nearly an entire inner volume of the waste discharge pipe 18.
  • this waste discharge pipe plug 20 comprises a downwardly open casing 21, a plug body 22 fitted into the casing 21, and a rubber packing 23 screwed to a lower portion of the plug body 22.
  • the rubber packing 23 is screwed to the lower portion of the plug body 22 while leaving a certain gap from the plug body 22, and such a gap portion d is maintained in a covered state with the casing 21 so as to prevent the waste discharged out of the bowl 10 from coming into the gap portion d.
  • a water tank 24 is generally located at a rear portion of the bowl 10 and has in its lower portion a water discharge port 25 communicating with the water supply channel 12.
  • a water discharge port-opening/closing plug is securely seated onto the water discharge port 26 to selectively open and close the water discharge port 26.
  • a float 30 rising and falling pursuant to a water level and water supply port-opening/closing means connected to the float 30 are so installed within the water tank 24 as to shut off the water supply into the water tank 24 at a full water level by blocking the water supply port 34 connected to the water pipe with the rise of the float 30 and to enable the water supply into the water tank 24 prior to the full water level by keeping the water supply port 34 in an open state.
  • a water tank-opening/closing lever 38 of a seesaw type is pivotally supported within the water tank 24, a part of the water tank-opening/closing lever 38 is penetrated through one side of the water tank 24 and exposed to the exterior so as to enable its manipulation outside the water tank 24, and an inner end of the water tank-opening/closing lever 38 is connected to the water discharge port-opening/closing plug 28.
  • an inner end of the water discharge port-opening/closing lever 28 can be lifted by an artificial manipulation (that is, an action of pushing the exposed part of the water tank- opening/closing lever 38).
  • an auxiliary lever 40 of a seesaw type is hinged and connected at its inner end to the inner end of the water tank-opening/closing lever 38, and the waste discharge pipe plug 20 is connected to the inner end of the auxiliary lever 40.
  • the auxiliary lever 40 is pivotally disposed within the water tank 24.
  • An auxiliary water pail 42 is hinged and connected to the other end of the auxiliary lever 40 to assist the seesaw action of the auxiliary lever 40 by inflow or outflow of the fluxing water into or from the auxiliary water pail in accordance with the water level within the water tank 24 (hereto, a description will be followed in detail).
  • Figs. 3a and 3b shows a pre-operative state of the water closet of the present invention.
  • the float 30 In a state that the flushing water is fully contained within the water tank 24 (a state of being full of water), the float 30 is positioned on the full water level by buoyancy of the fleshing water and the auxiliary water pail 40 is also positioned nearly at this water level. If the float 30 rises to the full water level, the water supply port 34 is closed to shut off the water supply into the water tank 24, and the auxiliary water pail 42 comes to have a lighter weight than that of the waste discharge pipe plug 20 because it is not completely filled with the flushing water. Consequently, the waste discharge pipe plug 20 is in a state of blocking the outlet side 19 of the waste discharge pipe 18 while maintaining its lowered state.
  • auxiliary water pail 42 is compulsorily lowered by the seesaw action of the auxiliary lever 40 and simultaneously the flushing water within the water tank 24 flows into and fills the auxiliary water pail 42 through upper and lower holes formed in upper and lower portions of the auxiliary water pail 42, the auxiliary water pail 42 gets heavier and is naturally lowered to keep the connecting portion between the water tank-opening/closing lever 38 and the auxiliary lever 40 in a lifted state. Therefore, the waste discharge pipe plug 20 and the water discharge port-opening/closing plug 28 connected to the connecting portion between the water tank- opening/closing lever 38 and the auxiliary lever 40 maintain their open states.
  • the flushing water effluent from the water tank 24 is discharged through the water supply channel 12 and the open discharge channel 14 of the bowl 10 together with the waste.
  • the flushing water with the waste can be discharged in a natural manner, not in a forced manner, because the waste discharge channel 14 is declivous toward the waste discharge pipe 18.
  • the discharge channel 14 has a slight inclination, the flushing water can be prevented from splashing when the waste comes into the water. It is believed that this is because the dropping impact is absorbed due to the shape of the discharge channel 14 when the waste is dropped.
  • the waste discharge pipe 18 is located at the center of the width b of the bowl 10, it is possible to slim the shape of the bowl 10 by narrowing the both sides of the bowl 10 (indicated by chain lines "A" in Fig. 3b) in so far as the waste discharge pipe 18 is not exposed in a front view of the bowl 10. This results in an effect of minimizing volume of the bowl 10.
  • the gap portion d between the plug body 22 and the rubber packing 23 of the waste discharge pipe plug 20 serves as a spare space, which enables the rubber packing 23 to seal the outlet 19 of the waste discharge pipe 18 even when the rubber packing 23 does not exactly coincide with the outlet 19.
  • the casing covering the gap portion 21 is a useful component for interrupting the waste in advance.
  • the plug body 22 and the rubber packing 23 respectively have a through hole 22a, 23 a extending in longitudinal directions thereof, and an auxiliary pipe 25 having a hook-shaped flow channel 25a is mounted to an upper end of the through hole 22a of the plug body 22. Accordingly, when the water level of the flushing water within the waste discharge pipe 18 is higher than the top of the waste discharge pipe plug 20, the excessive flushing water is discharged into the waste box 16 8
  • the flushing water with the waste is discharged in a natural manner, water can be saved and noise can be reduced.
  • the water discharge port-opening/closing plug and the waste discharge pipe plug are compulsorily operated by means of the respective levers, an opening time of each plug can be exactly regulated, thereby improving the reliability of water closet products. It is also possible to modify a shape of the bowl, and in particular, to reduce a width between both sides of the bowl, by selecting a position of the waste discharge pipe.
